In the scene, Jacqui, 47, is spotted trying to earn 12 stars in the difficult Sunday Slam challenge alongside popular co-star Justin Lacko, 28.
"We can't show you much, but what we can tell you is tonight's Trial involves Jacqui Lambie, a large boulder to the face and an ambulance," the caption mysteriously read.
Justin and Jacqui's newest challenge had the two going through an obstacle course while wearing huge elephant feet.
At one point, Jacqui gets carried out in an emergency vehicle after a confronting boulder hit her on the head half-way through the obstacle course.
Fans were quick to send their good wishes to the star, with one writing: "I hope that Jacqui will be okay."
Meanwhile, another vented their frustrations at the producers as a result of the incident. "Completely negligent! So stupid," one commenter wrote.
Let's hope Jacqui is on the mend!
